[0053] According to the present invention, the expression "hydrophilic gelling polymer" designates a polymer capable of thickening an aqueous medium. Preferably, the thickening polymer has, at 1% in water or a 50 / 50 water / alcohol mixture by weight at 25°C, a viscosity greater than 100 centipoise at a shear rate of 1 s1. Viscosity can be measured using, in particular, viscometers or rheometers with a cone-plate geometry.

[0054] The hydrophilic gelling polymer is chosen from anionic acrylic copolymers.

[0055] For the purposes of the present invention, the expression “acrylic copolymer” designates a polymer resulting from the copolymerization of at least two chemically different monomers, at least one of which is chosen from unsaturated carboxylic acids, preferably acrylic acid or methacrylic acid.

[0056] According to a particular embodiment of the invention, the anionic acrylic copolymer(s) are chosen from:

[0057] - anionic copolymers derived from at least one unsaturated carboxylic acid and of at least one ester of an unsaturated carboxylic acid and of a monoalcohol comprising from 1 to 6 carbon atoms and preferably from 1 to 4 carbon atoms;

[0058] - anionic associative acrylic copolymers, and

[0059] - their mixtures.

[0060] As used herein, the term "associative acrylic polymer" means an amphiphilic acrylic copolymer which is capable, in an aqueous medium, of reversibly combining with itself or with other molecules. It generally comprises, in its chemical structure, at least one hydrophilic region or group and at least one hydrophobic region or group.

[0061] The expression "hydrophobic group" designates a group or a polymer carrying a saturated or unsaturated and linear or branched hydrocarbon-based chain. When it designates a hydrocarbon-based group, the hydrophobic group comprises at least 8 carbon atoms, preferably from 10 to 30 carbon atoms, in particular from 12 to 30 carbon atoms, from 12 to 24 carbon atoms and preferably from 16 to 22 carbon atoms. Preferably, the hydrocarbon-based hydrophobic group comes from a monofunctional compound. For example, the hydrophobic group can be derived from a fatty alcohol, such as stearyl alcohol, dodecyl alcohol or decyl alcohol, or from a polyalkylenated fatty alcohol, such as steareth-50.

[0062] In the context of the invention, the anionic copolymer(s) derived from at least one unsaturated carboxylic acid and at least one ester of an unsaturated carboxylic acid and a monoalcohol comprising from 1 to 6 carbon atoms and preferably from 1 to 4 carbon atoms are different from the anionic associative acrylic copolymer(s).

[0063] The anionic copolymer(s) derived from at least one unsaturated carboxylic acid and at least one ester of an unsaturated carboxylic acid and a monoalcohol comprising from 1 to 6 carbon atoms and preferably from 1 to 4 carbon atoms are copolymers comprising, among their monomers, one or more unsaturated carboxylic acids, which are more particularly α,[3-monoethylenically unsaturated, and one or more esters of an unsaturated carboxylic acid, which are more particularly α,[3-monoethylenically unsaturated, and of a monoalcohol comprising from 1 to 6 carbon atoms and preferably from 1 to 4 carbon atoms.

[0064] More particularly, the unsaturated carboxylic acid, which is in particular α,[3-monoethylenically unsaturated, is a monomer corresponding to the formula (I) below: H2C----C..........C OH r! O (1)

[0065] in which R1 denotes H or CH3 or C2H5, which corresponds to acrylic acid, methacrylic acid or ethacrylic acid units.

[0066] Preferably, the other monomeric ester of an unsaturated carboxylic acid and of a monoalcohol comprising from 1 to 6 carbon atoms and preferably from 1 to 4 carbon atoms is a monomer of formula (II) below: H2C=C.........C.......OR2 R$ (H)

[0067] in which R1 denotes H or CH3 or C2H5 (i.e. acrylate, methacrylate or ethacrylate units) and preferably H (acrylate units) or CH3 (methacrylate units), and R2 denotes an alkyl group comprising from 1 to 6 carbon atoms and preferably from 1 to 4 carbon atoms.

[0068] As esters of an unsaturated carboxylic acid and of a fatty monoalcohol comprising from 1 to 6 carbon atoms according to formula (II), mention may be made more particularly of methyl acrylate, ethyl acrylate, propyl acrylate and butyl acrylate, and the corresponding methacrylates, methyl methacrylate, ethyl methacrylate, propyl methacrylate and butyl methacrylate.

[0069] According to one embodiment, these anionic copolymers can be crosslinked, for example, with a crosslinking agent, which is a well-known copolymerizable unsaturated polyethylene monomer, for example diallyl phthalate, allyl (meth)acrylate, divinylbenzene, (poly)ethylene glycol dimethacrylate or methylenebisacrylamide.

[0070] Among the anionic copolymers of this type, polymers consisting of the following monomers will be used more particularly:

[0071] (i) of an unsaturated carboxylic acid, which is in particular a,[3-monoethylenically unsaturated, corresponding to formula (I) below: H2C=C.........C— OH

[0072]

[0073]

[0074]

[0075]

[0076]

[0077]

[0078]

[0079]

[0080]

[0081] in which R1 denotes H or CH3 or C2H5, which corresponds to acrylic acid, methacrylic acid or ethacrylic acid units, and (ii) an ester of an unsaturated carboxylic acid and a monoalcohol comprising from 1 to 6 carbon atoms and preferably from 1 to 4 carbon atoms, of formula (II) below: H2C--C.........C —OR2 in which R1 denotes H or CH3 or C2H5 (i.e. acrylate, methacrylate or ethacrylate units) and preferably H (acrylate units) or CH3 (methacrylate units), and R2 denotes an alkyl group comprising from 1 to 6 carbon atoms and preferably from 1 to 4 carbon atoms, (iii) and optionally a crosslinking agent which is a well-known copolymerizable poly-ethylenic unsaturated monomer, such as diallyl phthalate, allyl (meth)acrylate, divinylbenzene, (poly)ethylene glycol dimethacrylate and methylenebisacrylamide. Examples of anionic copolymers as defined above are the crosslinked copolymer of acrylic acid and ethyl acrylate sold under the trade name Aculyn 33 by the company Rohm & Haas, which is in aqueous dispersion containing 28% by weight of active material, the crosslinked copolymer of methacrylic acid / ethyl acrylate in the form of an aqueous dispersion at 30% by weight (INCI name: Acrylates Copolymer) sold under the name Carbopol Aqua SF-1 Polymer by the company Lubrizol, and the copolymer of (meth)acrylic acid and a C1-C4 alkyl (meth)acrylate sold under the name Synthalen W400 by the company 3V Sigma, at 30% by weight of active material in water. Preferably, these anionic copolymers are chosen from crosslinked copolymers of (meth)acrylic acid and a C 1-C 4 alkyl (meth)acrylate, and better still from crosslinked copolymers of (meth)acrylic acid and ethyl (meth)acrylate. Among the anionic associative acrylic copolymers which can be used in the context of the invention, we can cite: (1) copolymers derived from the polymerization of: (i) (meth)acrylic acid and / or its CrC4 alkyl ester (ii) a monomer of formula (III) below: CH? = CR' CH2 O Bn R (III)

[0082] in which R1 denotes H or CH3, B denotes the ethyleneoxy group (-CH2-CH2-O-), n is zero or denotes an integer ranging from 1 to 100 (in particular from 5 to 15) and R denotes a hydrocarbon-based group chosen from alkyl, arylalkyl, aryl, al-kylaryl and cycloalkyl groups comprising from 8 to 30 carbon atoms, preferably from 10 to 24 carbon atoms and even more particularly from 16 to 20 carbon atoms.

[0083] A monomer of formula (III) which is more particularly preferred is a monomer in which R' denotes H, n is equal to 10 and R denotes a stearyl group (Cl8).

[0084] These anionic associative polymers are described in patent EP-0 216 479.

[0085] Among these anionic associative polymers, those which are particularly preferred are polymers formed from 20% to 60% by weight of (meth)acrylic acid, from 5% to 60% by weight of C1-C4 alkyl (meth)acrylate, from 2% to 50% by weight of monomer of formula (III), and from 0 to 1% by weight of a crosslinking agent which is a well-known copolymerizable unsaturated polyethylene monomer, for example, diallyl phthalate, allyl (meth)acrylate, divinylbenzene, (poly)ethylene glycol dimethacrylate and methylenebisacrylamide.

[0198] For the purposes of the present invention, the expression "associative polymer" designates an amphiphilic polymer which is capable, in an aqueous medium, of reversibly combining with itself or with other molecules. It generally comprises, in its chemical structure, at least one hydrophilic region or group and at least one hydrophobic region or group. Non-ionic associative polyether polyurethanes

[0199] Non-ionic associative polyurethane polyethers generally comprise, in their chain, both hydrophilic blocks, usually of a polyoxyethylene nature, and hydrophobic blocks, which may be aliphatic sequences alone and / or cycloaliphatic and / or aromatic sequences.

In particular, it is possible that one or more pendant chains are provided. In addition, the polymer may comprise a hydrocarbon chain at one end or both ends of a hydrophilic block.

[0201] Polyurethane polyethers can be multi-block, in particular in tri-block form. The hydrophobic blocks can be at each end of the chain (for example: tri-block copolymer carrying a hydrophilic central block) or distributed both at the ends and in the chain (for example, multi-block copolymer). These same polymers can also be graft polymers or star polymers.

[0202] Non-ionic associative polyurethane polyethers comprising a fatty chain may be triblock copolymers, the hydrophilic block of which is a polyoxyethylene chain comprising from 50 to 1000 oxyethylene groups.

[0203] Nonionic associative polyurethane polyethers comprise a urethane linkage between the hydrophilic blocks, hence the name.

[0204] By extension, also included among the non-ionic associative polyurethane polyethers comprising a hydrophobic chain are those in which the hydrophilic blocks are linked to the hydrophobic blocks via other chemical bonds.

Assessment

[0286] The viscosity, pumping ratio and stability of each of the dye compositions and developer compositions obtained were evaluated. Viscosity

[0287] The viscosity of each dye or developer composition was measured to verify whether the composition is acceptable in terms of pumping and application.

[0288] Viscosity was measured by a Mettler RM 180 Rheomat with spindle #2 (for developer compositions) or #3 (for colorant compositions) at 25°C to verify whether the viscosity of the developer composition is in a range of 100 to 400 mPa.s, and whether the viscosity of the colorant composition is in a range of 600 to 1500 mPa.s. Pumping capacity

[0289] 110 g of a dye or developer composition were poured into a In a dual-pump package, 10 packages were prepared for each composition. For each package, the dye or developer composition was pumped by hand into a bowl until no composition could be pumped, and then the composition in the bowl was weighed as M (g). The pumping ratio is calculated as M / l 10 (%), then all the results for the 10 packages were calculated, and the average results of 10 packages were also recorded for the dye and developer. The target average pumping ratio is greater than 85% for all 10 packages. Stability

[0290] The stability of each dye or developer composition was evaluated as follows:

[0291] The composition was prepared and aged for 24 hours at room temperature, then contained in a cosmetic product bottle, then placed in an oven or refrigerator to be stored for a period of time:

[0292] 45°C: 1 month or 2 months;

[0293] Room temperature (20°C to 25°C): 1 month or 2 months;

[0294] 4°C: 1 month.

[0295] Then, it was checked whether the appearance was visibly changed.

[0296] If there is no phase separation after storage, the composition is considered stable.

[0297] In case of phase separation after storage, the composition is considered unstable.

[0298] The viscosity, pumping ratio and stability of each developer composition and dye composition were summarized in Table 4.

[0300] The application property, the running problem and the viscosity of the mixtures obtained by mixing a colorant composition and a developer composition were evaluated. Application Property

[0301] Each of the developer compositions of Inventive Examples 1 and 2 and Comparative Examples 1 to 3 as shown in Table 2 and the dye compositions of Inventive Examples 3 and Comparative Examples 4 and 5 as shown in Table 3 was mixed at a ratio of 1:1 by weight. The time T required to uniformly apply the mixtures to half a mannequin head by hand was recorded and compared, each mixture having been applied twice by different in-house hair experts, then the average time was calculated and the scores were given according to the following standard.

[0302] 10: T < 100 seconds;

[0303] 9:100 < Tel 10 seconds;

[0304] 8:110 <T<120 secondes ;

[0307] 5:140 <T<150 secondes ;

[0308] 4:150 <T<160 secondes ;

[0309] 3:160 <T<170 secondes ;

[0310] 2:170 <T<180 secondes ;

[0311] 1 : > 180 seconds. Leakage problem

[0312] The existence of a problem of dripping during the application of the mixtures obtained was observed by the experts. Viscosity

[0313] In addition, the viscosities of the obtained mixtures were measured by a Mettler RM 180 Rheomat with spindle # 3 at 25 °C to verify whether the viscosity of each mixture is within the range of 600 to 1500 mPa.s.

[0314] The results on application property, sagging problem and viscosity were summarized in Tables 5 and 6.

[0315] [Table 5] Table 5 El. 1+ EI. 3 El. 2+ EI. 3 El. 1+ EC. 4 El. 1+ EC. 5 El. 2+ EC. 4 El. 2+ EC. 5 EC 1+ EI3 EC 1+ EC. 4 EC 1+ EC. 5 Viscosity (mPa.s) 1320 670 1980 2150 1650 1840 230 450 380 Application score 9 9 6 5 7 6 9 9 9 Run-out problem NO NO NO NO NO NO YES YES YES

[0317] It can also be seen from Table 4 that the compositions of inventive examples 1 to 3 are stable and have viscosities suitable for pumping.

[0318] It can also be seen from Table 4 that the compositions of Comparative Examples 2 to 5 are not desired due to too high viscosity or poor stability.

[0319] It can be seen from Tables 5 and 6 that the mixtures obtained from kits according to the present invention have a suitable viscosity, and can be easily pumped and applied, without there being any problem of running during application. And the mixtures obtained with the developer composition of Comparative Examples 1 and 3 have too low viscosities and may cause a problem of running during application.
